' like, and comprises a tank mounted on wheels and provided with reciproccting scrubbin brushes at the front and with a.

cloth which follows the brushes and wipes up the floor, the dirty water being wrung from the cloth, which has the form of 'an endless belt which travels along the floor under the tznk and thence upwardly over the tank where the water is squeezed therefrom. v

The invention is characterized by im roved means for operating the belt and or reciprocating the scrubbing brushes, as well as i supplyingwater to the brushes bl means of osprey pipe leading from the tan r to position above the front ends of the brushes.

In the accompanying drawings Fi ure 1 is a side elevation of the machine. ig. '2 is a to plan view. Fig. 3 is a front elevation-o a portion of the operating mechanism. Fig. 4 is a front elevation of a por tion of the device showing the sprinkler and two scrubbing brushes as operated in conjunction. Figs. 5 and 6. are details of the machine, that will be more clearly defined in the description of the device.

The construction of the machine is as follows. Two independent side pieces (7) and (8) are provided which constitute a frame and which are rnvided with handles (9) for use in pushing; the device along. The side pieces ('7) and (8) are joined by the front and lower cross pieces (10) and {11) which are secured to the sauna, and these pieces also form a support for the water pun or receptacle (12). The said pan is divided into two separate compartments (l3) and (14) the object of which is described below. Compartment (13) is rovided with two valves (15) and (16) the ornier being used to regulate the su ply of water that may be admitted throng it to conipartment (i3) and the latter so regulates the supply through it into pipe (17 which connects with the sprinkler pipe (1'3) at the front of the device.

The entire machine is supported upon the rubber tired wheels (19). The two rear wheels are rotatably secured-to the. sides 4 (7) and (8) and the t.wo front ones are mounted on shaft'(20) which has a bearing at either end in the frame. Nearthe rear end of side (7) of the frame is a bracket (21) which carries a shnft (Q2) and with it a hand wheel ('23) and a sprocket wheel (24). The sprocket wheel (24) car ries a chain (25) which also engageswith a secondary sprocket wheel (29), on shaft 27) on which is secured a bevel ear 11 vertical shaft (29) another icvel gear (30) is secured which engages with bevel gear (28). A worm (34) is secured to shaft (29') near its lower end, and the up )er end is provided with a ball fly on be. once (72) which assists in the operation of the device. The brackets (32, 33 and 3t) serve as supports and contain bearings for the shafts (27) and (29') respectively. Worm (31) engages with the worm gear 35) which is secured to the rotatable shaft 36). This shaft also carries .1 sprocket wheel (37). a spur gear (38:) and a roller (39). The said spur gear ('38) engages with another spur gear (40) of the saintdiameter which is secured on rotatable shaft (41) which carries a. roller (42) of the same dimensions as roller (39) with which it eooperates.

The sprocket wheel ("37) on shaft (36) carries a chain (43) which engages with sprocket (4-1) on shaft (43). This shaft als carries a spur gear (46) and a spur pinion (47), which latter engages with the spur gear (48) on shaft (20). The spur gear ltfiaiso engages with the spur pinion (50) \\'hich is scoured to rotutai h shaft-dbl).

This shaft carries a series of ec ciztz'ics (52.) that are connected to and are instrumental in moving the scrub brushes forward and backward as the shaft revolves. The construction of the eccentric urgether with its relation to o ierating the brush may be seen in Fig. 5. n this construction the middle brush (53) is made to work opposite in motion to that of the side brushes (54).

A thin, and durable band (55) is arranged around the eccentric and is pivotally attached to brackets (56) near the rear of the brushes, and above'the same. The eewhere the ban placed in centric moves within the band thereb producing a horizontal movement 0 the brushes when the device is in operation.

Near the front of the machine and secured to the sides (7 and (8) is a cross piece (57) which assists in holding the frame rigid. Through this said piece a number of screws (58) are inserted, equal in number to the number of brushes used. The screws are pivotall secured in the springs 59) resting on the acks of the brushes. he ends of the springs (59)- operate in ooves, (60) which are provided the entire ength of the brushes, and serve as guides for the ends of said 5 rings. The springs supply pres sure to the brushes which 13 necessary in operation and the screws (58) are provided to adjust or regulate the tension.

Fig. 4 shows a modification which illus trates the manner of usin two brushes in conjunction with each at er. The brush (54) onthe side scrubs the mop board of a room and the other scrubs the floor. The same figure shows the sprinkler pipe (18) Bith holes (61) through which the water ows.

The side (8) of the frame has a slot or recess (62) to rovide an o ening to admit the wiping oth (63). e joint is supplied with the fasteners (64) to make it m. However before the WlPlIl cloth is osition the top roller 42) is removed. ig. 6 illustrates a. portion of the mechanism that removably retains the said roller. The wiping cloth is carried by the thin plate (65) at the top and rear of the tank and by the rollers (66) which are mounted at to and bottom between the front ends of t e side pieces (7) and (8) with bearings in the same. 5

Another feature in connection with the device is the provision made for heating the water as it is supplied to the receptacle pig- !vided for the same as previously descri A gasolcne tank (67) is secured toside 8) of the frame, and is provided with a valve (68 in a pipe (69) which leads from the tan to a series of burners (70) .underthe water tank. The burners are so arr-an that the flame from the same passes through a perforated plate (71) before acting upon the bottom surface of the water receptacle.

The compartment (13) of the said water receptacle is provided for clean water and compartment (14) for dirty water that may be moving from the wiping cloth in passing between .the rollers (39) and (42) whi operation.

The device is hand 0 rated as shown, but the construction is sac that it may be electrically operated if desired by attaching a motor and supplying a transmission gear w so is located.

ings to specify the direction of a number'of .the parts.

, The operation is as follows: The hand wh'eel should be operated in the direction indicated by the arrow. The chain turns sprocket wheel (29) and in so doing turns the shaft 27) together with the other mechanism in irect connection withit. Fowcris in turn then transmitted to the vcrticai shaft (29') and it is thereby used to revolve the rollers S139) and (42). The sprocket (37) carries c power to s rocket (44) by means of the chain (43). The rotatable motion of shaft (45) transmits power to shaft (20) and (51) respectively, thereby .crcating a horizontal movement of the brushes at the front of the machine and also revolves the driver wheels (19 located on said shaft. This movement 0 the drivers pushes the machine forward. Small pins (74) are insorted at either end of shaft (20) to secure the wheels (19) and ma allow the drivers to revo ve freely on the shaft when not in operation. As the ma-- chine advances across the floor in o nation the wiping cloth (63 is pulled a mg the scrubbed portion of t e floor thereby sealiing up all the water. The rollers (3 and (42) actuate the cloth and as the cloth passes between them they serve the purpose of a wringer and the dirty water is deposi ed in compartment (14) of the water receptacle (12). The mechanism rovided for a mi ing tension to roller (42) is shown in 1g. 6. It consists of a slide arrangement which fits in a oove provided for t e same-in frame 26; iumeral (75) indicates the 0 his in the bearing block (75') for one an of s aft (41 and this block is slidable up and'dowr.

in e frame (76) for adjustment, being prothe front thereof, a cross piece between said.

side ieces, a plurality of longitudinally mova le scrubbers located side by side under said cross piece, screws extending throu h the cross piece, springs connected to t c lower ends of' the screws and having a slidable connection at the backs of the scmb'sers, means to reciprocate the scrubbers, and means to'au ply water from the tank to the bcrubhersyt 6 screws bein adjustable to vary; the pressure. of the springs of the backs performthe function of a wringer when in of t e scrubbers.
